Lancôme had offered the lower court an expert report of a physical-chemical analysis of the two perfumes. The report concluded that, given the fact that there are hundreds of different components that could have been used, it is highly unlikely that it is a coincidence that Kecofa used 24 of the exact components out of the 26 in total used by Lancôme. The 25th ingredient was a cheaper substitute of the remaining Trésor component. Since the expertise of the report was not denied by Kecofa, nor the accusation of copying, the Court concluded that Kecofa must have copied Lancôme’s product and therefore violated Lancôme’s copyrights.
